Which of the following is not a component of a nucleotide?

Explanation:
A nucleotide is made up of a five-carbon sugar, a phosphate group, and a nitrogenous base. The sugar forms the backbone, the phosphate group links sugars together to build the chain, and the nitrogenous base encodes genetic information by pairing with a complementary base. A fatty acid belongs to lipids, not nucleotides, so it is not part of a nucleotide. That’s why fatty acid is the correct choice as something that is not a nucleotide component.
